Teko Telecom Modular off-air Repeaters represent the ideal solution to enhance and optimize cellular coverage, providing a flexible and cost-effective alternative to dedicated BTSs or Node Bs.

Modular off-air Repeaters are multi-band multi-operator systems, obtained by proper combination of the components of Sirius Master Unit, our versatile modular rack-based platform: their modular design and transparency to protocol and modulation provide a wide range of different solutions designed to be easily expanded, upgraded or integrated into existing Coverage Systems.

Architecture

To obtain Modular Off-Air Repeaters the Master Unit is equipped with Digital Donor Front Ends, providing the off-air RF interface towards the signal source (BTS, Node B, e-Node B, Repeater) and Service Front Ends, providing wireless signal to the area to be covered.

No physical connections are required between the Modular Repeater and the Cellular Network as a Donor Antenna, connected to the Digital Donor Front End, picks up the signal from distant macro cell towers.

Off-air Modular Repeaters can be equipped with one Donor Front End or more Donor Front End modules to make multiple configurations available.
A single-band single-operator Repeater can be set-up combining a Digital Donor Front End Module and a Service Front End Subrack.
Up to 4 Digital Donor Front Ends can be connected to a single Service Front End to obtain a single-band 4-operator Off-air Repeater.
Digital Donor Front End Modules can be connected to different Service Front End Subracks to provide multi-band/multi-operator Repeaters, operating over different frequencies and with various frequency combinations in the 380 to 2700MHz frequency range.

The Master Unit, configured to provide Modular Repeaters, also hosts the Supervision Module, for the management of the Modular Repeater: a PC connected to the IP address of the Supervision Module, allows easy local and remote control of the Repeater via Teko Telecom Management tools.
